current matching accuracy might be compromised by a partial short in one string, which may not trigger the full 6.3V6.3 cap V LEDX_OV threshold but can cause uneven wear. MP3378E - Monolithic Power Systems

The device includes recoverable thermal protection. If the junction temperature exceeds its safety threshold, the IC shuts down and resumes operation once it cools. The "Protection Pin" Logic (UPD)

If an LED string is disconnected or "open," the IC will keep increasing the output voltage. The OVP pin detects this runaway voltage and shuts down the driver once the safety threshold is reached.

It is typically connected to a resistor divider from the step-up converter's output to ground. This allows users to program the specific voltage level at which protection activates. Comprehensive Protection Features current matching accuracy might be compromised by a

If you want, I can:

The MP3378E integrates a step-down converter to create an internal bus voltage (e.g., 3.3V or 5V). This converter has its own set of protections. The "Protection Pin" Logic (UPD) OCP, OTP, UVP,

conditions across its four channels to prevent uneven brightness or circuit damage. WLED Controller Safety : Features Over-Current Protection (OCP) Over-Temperature Protection (OTP) Under-Voltage Protection (UVP) Over-Voltage Protection (OVP) Component Monitoring : Specifically includes inductor and diode short protection

The MP3378E does not rely on a single, isolated "protection pin." Instead, its protection loop functions as a network across multiple dedicated terminals. The IC constantly samples conditions at key interface pins to ensure neither the buck converter nor the WLED boost controller suffer permanent damage. 1. Over-Voltage Protection (OVP Pin)

The is a highly integrated single-chip solution designed for monitor applications, combining a 4-string White LED (WLED) step-up controller with a high-efficiency buck converter. Central to its reliability is a robust suite of protection mechanisms designed to prevent device failure and ensure long-term stability in display backlighting. Core Protection Infrastructure

: Features a simplified protection loop consisting of localized Over-Current Protection (utilizing Hiccup mode) and thermal shutdown safeguards.
